The mononuclear complexes [FeCpI(CO)₂] 1, [FeCp(CO)₂(η¹-dppm)]I 2, [FeCp(CO)(η²-dppm)]I 3, [FeCp(CO)₂(η¹-dppen)]I 5 and [FeCp(CO)(η²-dppen)]I 6 [dppen = Ph₂PC(=CH₂)PPh₂] have been synthesised and reacted with [Rh₂Cl₂(CO)₄] to produce heterobimetallic complexes of the type [CpFe(μ-CO)₂(μ-PP)RhX₂] (X = Cl or I). The structure of [CpFe(μ-CO)₂{μ-Ph₂PCH₂PPh₂}RhI₂] 4 has been determined by X-ray crystallography.
